Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system for ventilation and dehumidification,

The present invention relates to an air conditioning system, and more particularly, to a ventilation system for ventilating indoor air using one air conditioner and a dehumidifying function for removing moisture from moist air and supplying dried air back to the room And moreover, a technique for selectively applying ventilation and dehumidifying functions to a plurality of rooms.

Generally, a ventilation device using a fan is installed in the bathroom of the building, and the contaminated air in the room is exhausted to the outside by driving the fan. Such a ventilation device can also discharge humid air from a bathroom, but it is difficult to expect a dehumidifying effect with a simple air discharge.

Furthermore, there is no separate ventilation in the dressing room adjacent to the bathroom, so moldy can be caused by the humid air entering the bathroom.

In addition, there is a need to remove moisture from other rooms, such as a multi-use room where laundry is dried. However, even if ventilation facilities are installed, the effect of dehumidification is not so great.

For this purpose, it is possible to remove moist air by providing a separate dehumidifier in the dress room or the utility room. However, there is a problem in that a separate space for installing the dehumidifier is necessary as well as a cost for purchasing the dehumidifier.

On the other hand, Korean Patent Laid-Open No. 10-2002-0001137 is known as a conventional technique for controlling indoor humidity.

The present invention has been conceived in order to solve the problems of the conventional art as described above, and it is an object of the present invention to provide an air conditioner having a fan and a dehumidifying part by connecting a plurality of rooms with pipes to exhaust contaminated room air, And the air can be introduced into the room again, thereby providing an air conditioning system capable of selectively ventilating and dehumidifying a plurality of rooms with one air conditioner.

The main body of the air conditioner is provided with a second inlet port, a first outlet port and a second outlet port. The second inlet port is connected to a flow path C of a second damper as a selective damper, and the first outlet port is connected to a general damper A third damper is connected to the second damper, and a flow path C of a fourth damper as a selective damper is connected to the second outlet, an intake pipe of the first chamber is connected to the flow path A of the second damper, An inlet pipe of the second room is connected to the flow path A, an air supply pipe of the first room is connected to the flow path A of the fourth damper, an air supply pipe of the second room is connected to the flow path B of the fourth damper, The ventilating duct connecting pipe is connected to the third damper so that the entire damper is blocked by the control of the control unit in the ventilating mode operation of the first room or the second room and the third damper is opened, 2 The damper can be set according to the room in which the ventilation mode is selected. The passage B is connected to the passage C so that the air of the first room or the second room flows through the second inlet and escapes to the ventilation duct side through the first outlet as the fan is driven, The flow path of the third damper is shut off under the control of the control section when the dehumidification mode of the room is operated, and the flow path A or the flow path B of each of the second damper and the fourth damper is connected to the flow path C The air in the first room or the second room may be introduced through the second inlet and dehumidified and then supplied to the respective rooms through the second outlet according to the driving of the fan and the dehumidifier.

The main body of the air conditioner is provided with a first inlet, a second inlet, a first outlet, and a second outlet. The first inlet is connected to a first damper, which is a general damper, and the second inlet, A third damper as a general damper is connected to the first discharge port and a flow path C of a fourth damper as a selective damper is connected to the second discharge port, The damper is connected to the ventilation pipe of the first room, the inlet pipe of the first room is connected to the flow path A of the second damper, the inlet pipe of the second room is connected to the flow path B of the second damper, The third damper is connected to the ventilating duct connecting pipe, the flow path A of the fourth damper is connected to the air supply pipe of the first room, and the air supply pipe of the fourth damper is connected to the air supply pipe of the second room, When the ventilation mode of the second damper is operated, The first damper and the third damper are opened so that the air in the first room flows into the first room through the first inlet and flows toward the ventilation duct through the first outlet. The flow path of the first damper and the third damper is shut off under the control of the control unit when the dehumidification mode of the first room or the second room is operated and the second damper and the fourth damper are operated in accordance with the selected room Each of the flow passages A or B is connected to the flow passage C so that the air in the first room or the second room flows through the second inlet and is dehumidified according to the driving of the fan and the dehumidifying part, As shown in FIG.

As described in detail above, according to the air conditioning system capable of selective ventilation and dehumidification of a plurality of rooms according to the present invention, it is possible to simultaneously perform the ventilation function and the dehumidification function through one air conditioner. That is, in the conventional ventilation system installed in the bathroom, the dehumidifying effect can not be expected to be largely expected by simply taking indoor air out to the outside. In the present invention, however, ventilation is performed by driving the fan, And the dry air is introduced into the room again to obtain a sufficient dehumidifying effect.

In addition, the present invention has an advantage in that it is possible to ventilate and dehumidify a plurality of rooms in a bathroom, a dressroom, a utility room, and a kitchen, all of which require smell or moisture removal through one air conditioning device. In other words, conventionally, since a separate dehumidifier must be provided for each space requiring dehumidification, a separate space for installing a dehumidifier is required as well as a cost for purchasing a dehumidifier is required. However, in the present invention, Both the ventilation and the dehumidification can be performed (or selectively performed), which is advantageous in cost reduction and space required for installation.

Meanwhile, the air conditioner of the air conditioning system according to the present invention is capable of selectively controlling a plurality of rooms because a selectable damper that connects a plurality of rooms to one inlet and one outlet is applied.

In other words, if a pipe connected to several rooms is connected directly to the main body, the size of the main body is increased as the number of the inlet is increased. In addition, the control is complicated because a damper must be installed for each pipe and operated separately. However, in the present invention, the T-shaped blade in which the disk and the semi-circular disk are combined rotates in the connection part constituting the T-shaped flow path, and the flow path connection is selected or all connections can be made, It is possible to connect a plurality of pipes and to control only one blade, so that the design of the control unit can be simplified.

In the present invention, since the constant air flow rate BLDC motor is applied to operate the fan generating the air flow, even if the same air conditioner is installed in a high-rise or low-floor, the rotation speed is automatically controlled according to the air resistance, Therefore, it is not necessary to set the output setting of the fan driving motor for each layer differently.

The air conditioner 100 is installed at the optimum position in consideration of installation of the entire piping. For example, the bathroom 240 may be fixedly installed at a specific point on the ceiling, or may be installed in a wall through which the ventilation duct 210 passes.

The air conditioning apparatus 100 includes a main body 110 having a first inlet 111 and a second inlet 113 on one side and a first outlet 115 and a second outlet 117 on the other side, And a fan 120 and a dehumidifier 130 installed in the main body 110.

The fan 120 installed in the main body 110 rotates by the rotational power generated by the fan driving motor 121 to produce a flow of air. That is, the fan 120 allows the air to flow from the inlets 111 and 113 of the main body 110 toward the outlets 115 and 117.

The dehumidifying unit 130 is provided to remove moisture contained in the air introduced from the inlets 111 and 113 and circulate through the heat exchanging system such as a compressor 131, a condenser 132, an expansion valve 133 and an evaporator 134 A method of condensing and removing moisture in accordance with a change in the state of the refrigerant may be used.

The bathroom inlet pipe 242 and the D / R inlet pipe 251 are connected to the second inlet 113 through a second damper 114.

The second damper 114 has a unique structure so that the second inlet 113 can selectively connect the flow path with the bathroom intake pipe 242 and the D / R inlet pipe 251 connected to each other.

3 is a view for explaining a fourth damper 118 installed on the side of the second discharge port 117 of the main body 110. Fig. The fourth damper 118 and the second damper 114 are selectable dampers for connecting the two flow paths to one inlet or outlet. The fourth damper 118 and the fourth damper 114 are connected to each other through a fourth connecting portion 118e, The fourth damper blades 118a, 118b and 118c and the fourth damper motor 118d are connected to the second connecting portion 114e of the second damper 114, the second damper blades 114a, 114b and 114c, The description of the fourth damper 118 through FIG. 3 will be sufficient to explain the configuration and function of the second damper 114. FIG.

That is, referring to FIG. 3A, the fourth damper 118 includes a fourth connecting portion 118e which is formed so as to intersect with a flow path branched in one side direction of the flow path in the up and down direction and the flow path in the up and down direction, Fourth damper blades 118a, 118b and 118c provided in the fourth connecting portion 118e for selectively connecting the flow paths and a fourth damper motor 118d for rotating the fourth damper blades 118a, 118b and 118c . The flow path in the upward direction is called the flow path A 118eA, the flow path in the downward direction is referred to as the flow path B 118eB and the flow path in the sideward direction is referred to as the flow path C (118eC) in the fourth connection portion 118e do.

The fourth damper blades 118a, 118b and 118c provided at the intersections of the flow paths Ae, 118b and 118eC are formed by coupling a half disk to the center of the disk . Therefore, the fourth damper blades 118a, 118b, and 118c may be divided into three blades about a point where the disk and the half disk intersect. The three divided blades are referred to as a fourth damper blade a 118a, a fourth damper blade b 118b and a fourth damper blade c 118c for convenience, respectively. Here, the fourth damper blades 118a, 118b, and 118c need not necessarily be a disk or a half-disk, and may be formed in a different shape if they can be rotated 360 degrees while closely contacting the inner wall surface of the fourth connection portion 118e have.

These fourth damper blades 118a, 118b and 118c can be rotated by the fourth damper motor 118d to produce different flow path connection states as shown in Figs. 3 (a) to 3 (d). That is, as shown in FIG. 3A, three flow paths 118eA, 118eB, and 118eC are formed in a configuration in which the fourth damper blade b 118b and the fourth damper blade c 118c block the upper and lower portions of the flow path C 118eC, Are all blocked. On the other hand, as shown in FIG. 3 (b), the fourth damper blade a 118a and the fourth damper blade c 118c, which form a disk, extend from the left side of the flow path B 118eB to the upper side of the flow path C 118eC And the fourth damper blade b 118b is on the left side of the flow path A 118eA, the flow path C 118eC and the flow path B 118eB are connected and air can flow. A state in which the fourth damper blade a 118a and the fourth damper blade c 118c forming the disk are parallel to the connection direction of the flow paths A 118eA and the flow paths B 118eB as shown in FIG. The flow path A 118eA, the flow path B 118eB, and the flow path C 118eC are connected to each other if the fourth damper blade b 118b extends over the wall surface opposite to the flow path C 118eC. As shown in FIG. 3 (d), the fourth damper blade a 118a and the fourth damper blade c 118c, which form a disk, extend from the lower portion of the flow path C 118eC to the left side of the flow path A 118eA And the fourth damper blade b 118b is on the left side of the flow path B 118eB, the flow path C 118eC and the flow path A 118eA are connected to allow air to flow.

Of course, in FIG. 3 (a), the fourth damper blade b 118b and the fourth damper blade c 118c are placed above and below the flow path C 118eC, thereby blocking all the flow paths. However, The function of shutting off all the flow paths is performed even if the fourth damper blade a 118a and the fourth damper blade b 118b are located above and below the flow path C 118eC.

Namely, the selectable damper such as the fourth damper 118 corresponds to the fourth damper blade b 118b at the center of the original plate (corresponding to the fourth damper blade a 118a and the fourth damper blade c 118c) The other side of the disk opposite to the surface on which the half disk is fixed is to reflect the air flowing in the flow path and to send the air to the other side of the flow path. And closes the specific flow path among the three flow paths.

As described above, the second damper 114 is the same as the fourth damper 118, so that the description of the second damper 114 is omitted. Referring again to FIG. 2, The second inlet 113 of the main body 110 is connected to the flow path C 114eC of the first flow path 114e and the D / R inlet piping 251 connected to the dress room 250 is connected to the flow path A 114eA, The bathroom B (114eB) is connected to a bathroom intake piping (242) connected to the bathroom (240). The process in which the second damper 114 selectively connects the flow path according to the operation mode will be described again.

A first outlet 115 and a second outlet 117 are provided on the opposite side of the body 110 where the inlets 111 and 113 are formed.

The ventilation duct connecting pipe 244 is connected to the first outlet 115 through a third damper 116 as a connecting medium. That is, one side of the ventilation duct connecting pipe 244 is connected to the ventilation duct 210 and the other side is connected to the second outlet 117 provided in the main body 110 of the air conditioner 100 with the third damper 116 interposed therebetween. Lt; / RTI >

The third damper 116 includes a third connecting portion 116e for connecting the flow path of the first outlet 115 and the ventilation duct connecting pipe 244 and a second connecting portion 116e rotatably installed in the third connecting portion 116e, A third damper blade 116a that opens or closes the flow path, and a third damper motor 116d that generates power to rotate the third damper blade 116a.

The bathroom air supply pipe 243 and the D / R supply pipe 252 are connected to the second outlet 117 through a fourth damper 118 as a connection medium.

The fourth damper 118 is a selectable damper and has been described in detail above with reference to Fig. The second outlet 117 of the main body 110 is connected to the flow path C 118eC of the fourth connection portion 118e of the fourth damper 118 and the second outlet 117 of the main body 110 is connected to the flow path A 118eA of the dressing room 250 A D / R supply pipe 252 is connected to the D / R supply pipe 252, and a bathroom supply pipe 243 connected to the bathroom 240 is connected to the flow channel B 118eB.

The air conditioner 100 and the dampers 112, 114, 116, and 118 described above operate by outputting control signals from the controller 220 in response to a command input by the user through the operation unit 230. The user can select a bathroom ventilation mode, a bathroom dehumidification mode, a dressroom dehumidification mode, or a bath / dress room simultaneous dehumidification mode through the operation unit 230, and the air conditioning apparatus 100 and the dampers (112, 114, 116, 118) will be described in detail with reference to FIG. 4 through FIG.

4 is a view for explaining a state of an air conditioner and dampers when a bathroom ventilation mode is operated in an air conditioning system according to an embodiment of the present invention.

First, when the user selects the bathroom ventilation mode through the operation unit 230, the control unit 220 operates the first damper motor 112d and the third damper motor 116d to control the first damper blade 112a and the third damper blade 112b, The first connection portion 112a and the third connection portion 116e are opened.

The controller 220 operates the second damper motor 114d and the fourth damper motor 118d so that the second damper blades 114a, 114b, and 114c and the fourth damper blades 118a, 118b, (114eC, 118eC). Here, the second damper motor 114d and the fourth damper motor 118d may be a stepping motor capable of rotating at a predetermined angle according to a pulse signal, through which the second damper blades 114a, 114b, 114c And the fourth damper blades 118a, 118b, and 118c rotate in units of 90 degrees and can be converted into states as shown in Figs. 3 (a) to 3 (d). The second damper blade b 114b and the second damper blade c 114c block the upper and lower portions of the flow path C 114eC in the bathroom ventilation mode and the fourth damper blade a 118a and the fourth damper And the blade b (118b) also hits the upper and lower portions of the flow path C (118eC). Of course, if the second damper blades 114a, 114b, 114c and the fourth damper blades 118a, 118b, 118c are already blocking the respective flow paths C 114eC, 118eC, the second damper motor 114d and fourth The damper motor 118d does not perform a specific operation by checking the position of the blade.

Also, in response to the bathroom ventilation mode, the control unit 220 operates the fan driving motor 121 to rotate the fan 120. At this time, the dehumidifying part 130 does not operate. Air flows from the inlet ports 111 and 113 to the discharge ports 115 and 117 through the operation of the fan 120. The second damper 114 and the fourth damper 118 are in a shutoff state, Only the air inside the bathroom 240 moves along the bathroom ventilation pipe 241 so that the first damper 112 and the third damper 116 are in the open state and the first damper 112 and the first dam The air passes through the first outlet 115, the third damper 116, and the ventilation duct connecting pipe 244 to the ventilation duct 210.

Here, the ventilation duct 210 is a passage commonly used for taking out air to be exhausted from each floor of an apartment or a building to the roof. Therefore, in the exhaust process through the ventilation duct 210, the ventilation effect may vary due to different air resistance depending on the height of the floor.

For example, even if the fan driving motor 121 is operated with the same output, ventilation efficiency is low because the resistance of air is low in the generation near the roof, while the resistance of air is low in the low layer generation. For this purpose, in this embodiment, it is preferable to use a constant-flow-rate BLDC motor as the fan drive motor 121.

Referring to FIG. 9, FIG. 9 shows a constant-flow-rate BLDC motor and its driving circuit applied in the present embodiment. Referring to the driving circuit shown in Fig. 9, the constant airflow BLDC motor rotates the rotor through the PWM pulse, and checks the number of rotations of the rotor through the Hall sensor. When the number of revolutions decreases due to the external air resistance, So as to increase the number of revolutions, thereby enabling a constant air volume ventilation.

4, since the first outlet 115 is connected to the ventilation duct 210 through the third damper 116 and the ventilation duct connecting pipe 244, the indoor air But there is a possibility that the odor generated in the other generation flows backward if the third damper 116 is opened in a state in which the fan 120 is not driven. Of course, when the bathroom ventilation mode is not used, the third damper motor 116d operates in response to the signal from the controller 220 to shut off the third damper blade 116a to prevent reverse flow. However, if the third damper blade 116a is open and an accident such as a fire due to fire occurs, the third damper blade 116a is maintained in an open state and the ventilation duct 210 and the ventilation duct connection pipe 244), toxic gas may flow backward and cause danger. To this end, the third damper motor 116d is equipped with a condenser to charge the power source normally, and when a power failure occurs, a DC motor that automatically rotates the third damper blade 116a into a cutoff state by a power source charged in the condenser is used desirable.

The first damper motor 112d may also be a DC motor, but the third damper motor 116d can perform an automatic flow cutoff function during a power failure. Therefore, in terms of cost reduction, Motor may be used.

Here, if a power failure occurs irrespective of a user's intention and the flow path connecting the bathroom 240 and the dressing room 250 is opened, odor and moisture may be mixed with each other. It is preferable that a motor for automatically closing the flow path when power supply to the dampers 112, 114, 116 and 118 installed in the inlets 111 and 113 and the outlets 115 and 117 of the main body 110 is blocked is preferably applied. That is, the first damper 112 and the third damper 116, which are general type dampers, as well as the second damper 114 and the fourth damper 118, which are optional dampers, charge the condenser when the external power source starts to be supplied, When it happens, the motor is operated through the power supply of the charged capacitor so that the blade can cut off the flow path.

5 is a view for explaining a state of an air conditioner and dampers in a bathroom dehumidification mode in an air conditioning system according to an embodiment of the present invention.

When the user inputs the bathroom dehumidification mode through the operation unit 230, the control unit 220 operates the first damper motor 112d and the third damper motor 116d so that the first damper blade 112a and the third damper blade (116a). The control unit 220 operates the second damper motor 114d and the fourth damper motor 118d so that the second damper blades 114a, 114b, and 114c and the fourth damper blades 118a, 118b, The flow path B 114eB and the flow path C 114eC of the second connection portion 114e are connected to each other so that the flow path B 118eB and the flow path C 118eC of the fourth connection portion 118e are connected to each other, To be connected.

The control unit 220 operates the fan driving motor 121 to generate a flow of air through the rotation of the fan 120 and also operates the dehumidifying unit 130 to flow through the second inlet 113 Removes moisture from the air.

The humid air in the bathroom 240 flows into the flow path B 114eB of the second connection portion 114e along the bathroom intake piping 242 by the operation of the fan 120 and then flows into the flow path C 114eC of the second connection portion 114e, And flows along the flow path C 118eC and the flow path B 118eB of the second outlet 117 and the fourth connection portion 118e to be supplied to the bathroom supply piping 243 And then flows into the bathroom 240 again. The dehumidifying part 130 functions to condense the moist air in the air to remove moisture by changing the state of the refrigerant.

That is, the compressor 131 compresses the gaseous refrigerant to a high temperature and a high pressure state, and the high temperature and high pressure gas exiting the compressor 131 is converted into liquid in the condenser 132 to release heat. When the refrigerant passes through the narrow portion of the expansion valve 133 and the refrigerant enters the evaporator 134 after the speed of the fluid increases and the pressure decreases, the refrigerant absorbs the surrounding heat and evaporates to the gaseous state. When the humid air introduced through the second inlet 113 passes through the evaporator 134, the temperature of the air is lowered, the air reaches the dew point, and the water vapor in the air is changed into water. (132) and then exits to the second outlet (117). Therefore, the humid air introduced through the bathroom intake pipe 242 and the second damper 114 passes through the dehumidifying part 130 inside the main body 110, and then the moisture is removed. Then, the fourth damper 118 and the bathroom supply pipe The dehumidifying operation is performed while flowing into the bathroom 240 again through the opening 243.

Here, it is preferable that water collected while passing through the evaporator 134 is discharged through a separate pipe.

6 is a view for explaining a state of an air conditioner and dampers in a dress room dehumidification mode in an air conditioning system according to an embodiment of the present invention.

When the user inputs the dressroom dehumidification mode through the operation unit 230, the controller 220 causes the first damper 112 and the second damper 114 to be in a flow-cut-off state. Of course, there is no control if it is already blocked. The control unit 220 operates the second damper motor 114d and the fourth damper motor 118d so that the second damper blades 114a, 114b, and 114c and the fourth damper blades 118a, 118b, The flow path A 114eA and the flow path C 114eC of the second connection portion 114e are connected to each other so that the flow path A 118eA and the flow path C 118eC of the fourth connection portion 118e are connected to each other, To be connected.

The control unit 220 also operates the fan driving motor 121 and the dehumidifying unit 130. The humid air in the dressing room 250 flows into the flow path A 114eA of the second connecting portion 114e along the D / R inlet piping 251 by the operation of the fan 120, When moisture is removed from the dehumidifying part 130 after flowing into the main body 110 through the second inlet 113, the flow path C 118eC of the second outlet 117 and the fourth connection part 118e and the flow path A And flows into the dressroom 250 along the D / R supply pipe 252.

7 is a view for explaining a state of an air conditioner and dampers in a simultaneous dehumidification mode of a bathroom and a dressroom in an air conditioning system according to an embodiment of the present invention.

When the user inputs the simultaneous dehumidification mode of the bathroom and the dressroom through the operation unit 230, the controller 220 controls the first damper 112 and the second damper 114 to be in a flow cutoff state, The damper motor 114d and the fourth damper motor 118d are operated so that the second damper blades 114a, 114b and 114c and the fourth damper blades 118a, 118b and 118c are brought into the state (c) The flow path A 114eA, the flow path B 114eB and the flow path C 114eC of the second connection portion 114e are all connected and the flow path A 118eA, the flow path B 118eB, C 118eC are all connected.

In addition, the control unit 220 operates the fan driving motor 121 and the dehumidifying unit 130. The humid air in the bathroom 240 is supplied to the second inlet 113 via the flow path B 114eB and the flow path C 114eC of the second connecting portion 114e along the bathroom inlet pipe 242 by the operation of the fan 120 And the humid air in the dressing room 250 is also supplied to the second inlet port 131a via the flow path A 114eA and the flow path C 114eC of the second connecting portion 114e along the D / R inlet pipe 251, (Not shown). The moist air introduced from the bathroom 240 and the dressing room 250 is dehumidified by the dehumidifying part 130 and the dried air is discharged along the second outlet 117 to be discharged to the outside of the fourth connection part 118e, C 118eC and the flow path B 118eB to the bathroom 240 along the bathroom supply piping 243 and simultaneously the dried air flows through the flow path C 118eC of the fourth connection portion 118e and the flow path A R supply pipe 252 to the dressing room 250 through the drain pipes 118aA and 118eA.

As described in detail above, according to the air conditioning system capable of selective ventilation and dehumidification of a plurality of rooms according to the present invention, it is possible to simultaneously perform the ventilation function and the dehumidification function through one air conditioning system 100. That is, in the conventional ventilation system installed in the bathroom, the dehumidifying effect can not be expected to be achieved by merely extracting the indoor air to the outside. In the present invention, however, the ventilation is performed by driving the fan 120, ), Moisture can be removed from the humid air, and the dry air can be introduced into the room again to obtain a sufficient dehumidifying effect.

In addition, the present invention has an advantage in that it is possible to ventilate and dehumidify a plurality of rooms of the bathroom 240, the dressroom 250, the utility room, and the kitchen, all of which require smell or moisture removal through one air conditioning apparatus 100 have. In other words, conventionally, since a separate dehumidifier must be provided for each space requiring dehumidification, a separate space for installing a dehumidifier is required as well as a cost for purchasing a dehumidifier is required. However, in the present invention, Both the ventilation and the dehumidification can be performed (or selectively performed) for a plurality of rooms, so that there is an advantage that the cost is reduced and the installation space is reduced.

The air conditioning system 100 of the air conditioning system according to the present invention is capable of selectively controlling a plurality of rooms because a selective damper capable of connecting a plurality of rooms to one inlet 113 and one outlet 117 is applied to be.

That is, if a pipe connected to several rooms is directly connected to the main body 110, the size of the main body 110 becomes large due to an increase in the number of the inlet ports. In addition, the control is complicated because a damper must be installed for each pipe and operated separately. However, in the present invention, the T-shaped blade in which the disk and the half disk are combined rotates in the connection part constituting the T-shaped flow path and selects the flow path connection, or both, A plurality of pipelines can be connected and only one blade can be controlled, so that the design of the control unit 220 can be simplified.

Also, in the present invention, the constant air amount BLDC motor is applied to operate the fan 120 causing the air flow, so that even if the same air conditioner 100 is installed on the high floor or on the low floor, It is not necessary to set the output setting of the fan drive motor 121 for each layer differently because ventilation can be performed with the same air volume.

In addition, conventionally, in order to ventilate or dehumidify, indoor air is simply taken out of the room. In this case, the heated indoor air escapes and heat loss is inevitable. However, according to the present invention, since the indoor air is not simply exhausted but is introduced into the room again, energy loss can be prevented by the waste heat recovery function.

Meanwhile, in the air conditioning system according to the embodiment of the present invention, it is not possible to select the operation mode through the operation unit 230 or to select only the on-off function of the power supply. The air conditioning system may control the intensity of the rotation of the fan 120, The dehumidifying function may be automatically or manually operated depending on the humidity set in connection with the time, or the ventilation or dehumidifying function may be performed according to the reservation time.

Although the ventilation pipe 241 is connected to the bathroom 240 in the above-described embodiment, it is also possible to connect the ventilation pipe to the dressing room 250. In this case, a selective damper is applied to the first inlet 111, The ventilation of the bathroom 240 and the dressing room 250 is also possible by controlling the flow connection through the ventilation duct 220.

Also, although the bathroom 240 and the dressing room 250 are illustrated and described in the above-described embodiments, ventilation and dehumidification may be performed by additionally connecting the multi-use room or the kitchen to the kitchen. In this case, the selective damper can be overlapped to connect three or more pipes to one inlet or outlet. For example, the flow path C of the optional damper is connected to the flow path B (114eB) below the second connecting portion 114e of the second damper 114. [

And in the embodiments described above, the packing may be applied around the blades for reliable flow path sealing.

In addition, the position of the pipes installed in the bathroom 240 and the dressing room 250 in the above-described embodiment is as follows. Since the air having moisture is sinking downward, the entrance of the bathroom intake pipe 242 is opened at the bottom of the bathroom 240 It is preferable to be installed at a height-off position, for example, a knee height of a person. Also, since humid air may enter the outside through the door, it is preferable that the outlet of the bathroom air supply pipe 243 through which the dry air flows into the room is communicated to the upper portion of the door.

Of course, the bathroom ventilation pipe 241 and the bathroom intake pipe 242 are separately provided so that the humid air can be introduced from the optimum position. However, if the air intake pipe 242 and the bathroom intake pipe 242 are not taken into account, the number of the pipes and the number of the inlets 111, You can give it.

For example, the first inlet 111 is removed from the main body 110 of the air conditioner 100 and the bathroom ventilation pipe 241 is not separately installed. In this case, the ventilation mode and the dehumidification mode can be operated in a state in which the bathroom air intake pipe 242 and the D / R air intake pipe 251 are connected to the second damper 114 installed in the second inlet 113. When the bathroom ventilation mode is selected, the control unit 220 blocks all the flow paths of the fourth damper 118 and the flow path B 114eB of the second damper 114 in a state in which the third damper 116 is opened. So that the air in the bathroom 240 can escape into the ventilation duct 210 by the operation of the fan 120. [ Of course, if the flow path A 114eA and the flow path C 114eC are connected in this state, the dress room ventilation mode is also possible. On the other hand, if the dehumidifying mode of the bathroom 240 or the dressing room 250 is selected, the flow path of the third damper 116 is shut off and the connection of the second damper 114 and the fourth damper 118 is adjusted, So that the dried air is supplied to each room.

Furthermore, the connection between the air conditioner 100 and the piping can be further simplified to enable selective ventilation and dehumidification. 8, the first inlet 111 and the first outlet 115 are removed from the main body 110 (in this case, the bathroom ventilation pipe 241, the first damper 112, and the third damper 116 And the D / R inlet pipe 251 is connected to the second damper 114 provided at the second inlet 113, and the second damper 114 connected to the second outlet 117 The ventilation duct connecting pipe 244 is connected to the flow passage A 118eA of the damper 118 and the bathroom air supply pipe 243 and the D / R supply pipe 252 is connected. In this case, when the fan 120 is operated while the flow path A 118eA and the flow path C 118eC of the fourth damper 118 are in communication with each other, depending on the channel connection state of the second damper 118, Ventilation mode and simultaneous ventilation mode are possible. On the other hand, after the passage B 118eB and the passage C 118eC of the fourth damper 118 are connected to each other, the state of the fifth damper 119 connected to the passage B 118eB and the state of the second damper 118 When the dehumidifying unit 130 is operated by adjusting the state, a bathroom dehumidification mode, a dressroom dehumidification mode, and a simultaneous dehumidification mode are possible.

Consequently, in the present invention, it is possible to selectively ventilate and dehumidify a plurality of rooms through various applications and controls of the selectable dampers (114, 118, 119) without enlarging the size of the air conditioner 100, But it can be variously changed.

The foregoing description of the preferred embodiments of the present invention has been presented for the purpose of illustration and it will be apparent to those skilled in the art that various modifications, additions and substitutions are possible within the spirit and scope of the invention, And additions should be considered as falling within the scope of the claims of the present invention.
